Fig. 1From: Characterization and adaptation of Caldicellulosiruptor strains to higher sugar concentrations, targeting enhanced hydrogen production from lignocellulosic hydrolysatesDevelopment of C. owensensis, C. kronotskyensis, C. bescii, C. acetigenus and C. kristjanssonii adapted to higher sugar concentrations. Values in green indicate adaptation steps were completed in flasks on stated concentrations of glucose. Values in yellow indicate the final adaptation step and therefore the highest concentration of glucose that the species can be grownBack to article page
